| Re: when should I replace lights? I replace my aquasun VHO's every 9 months - but have left the Actinics on for up to 16 months thinking they would not shift as much. Lessons learned- I guess I will be buying some more VHO bulbs. Anybody have any suggestions were I can get them- 46.5 inch is what I use. My local stores sell them for over $40 each ( ouch!!) - so I will be ordering via the internet. Thanks. |
